LIQUID-N OZ ZLE.

Application filed September 28, 1998. Serial No. 455,020.

To all whom it 'may concern: y

le it known that. I, .hues (ir. l\I.\s'r|N, a

citizen' of the United States, residing at Chi-v cago, county of Cook, and State of Illinois,

fol-lowing is a specification.

My invention relates to nozzles and more specifically to that class of the same designed for the ejection of liquids.

The object of my invention is toprovide a device of the character mentioned which will be adapted to be attached to/the shank of a suitable stop-cock, and one which will eject the liquid passed through it into `a thin, mist-'like spray.

A further object of my invention is to provide a nozzle which will be so constructed as to be of the highest possible efliciency in serving a purpose as stated, and one which will be extremely simple of construction, hence of low cost to manufacture.v

Other objects will appear hereinafter.

With these objects in view my invention consists generally ina nozzle characterized as above mentioned, and in certain details of construction and arrangements of parts all as will be hereinafter' fullyA described and particularly pointed out in the claim. i

My invention will be more readily understood by reference to the accompanying drawings forming a part of this specification, and in which, y

Figure 1 is a side elevation of an ordinary stop-cock, the same being provided with the preferred form of my device, Fig. 2l is an enlarged longitudinal section through my device detached, Fig. 3 is an end elevation thereof, Fig. 4 is a transverse `.section taken on the line mof Fig. 2, and Fig. 5 is an enlarged detail .erspective of the interior helically groovet member' embodied in my invention. j

Referring now to the drawings, 1 indicates a preferablycylindrical member, the same being constructed of any suitable metal, but preferably brass'. Said member is provided with a centrally positioned, longi- -tudinally extending circular perforation 2,

ing a mouth or orifice 5, said orifice being I of a less diameter than the remaining' extent of said perforation. Thediameter 'of saidu perforation issubstantially constant to within a short distance, say about l 16th of an inch from the forward extremity thereof, at which point it tapers rather abruptly sayI at an angle of approximately (i0 degrees to the mouth or orifice 5. It is understood however, that the dimensions above quoted are given merely to make the construction of the device clearer, hence', I do not wish to be limited thereto. The outside surface of the forward end portion 4 said member 1 is also provided with a conical depression or recess 6 leading to the orifice 5 thereof, thereby forming said orifice knife-edged as clearly shown in Fig. 2 of the accompany- Specification of Letters Patent. Patented A ug. 31, 1909. i.

ing drawings for a purpose hereinafter` stated. Adapted to be fixed within said member 1 the forward extremity of the same preferably abutting the shoulder 7 provided in said member 1 in order that a chamber 8 shall be formed at the forward extremity 'surface of themember 1 as clearly shown in Figs. 2 and 4. The rearward end lportion of the member 1 is internally threaded as at 12, adapting said member to be threaded,

hence fixed, upon the shank 13 of `a stop- `cocnk of suitable construction, indicated inv the drawing by 14, in such a manner that a chamber 15 shall be formed between the adjacent extremitiesY ofthe stop-cock shank and the member 9; v

In operation the liquid is admitted. through the stop-cock 'and discharged into the cham? ber 15, from which chamber it enters the helicalrgrooves V10 in the member" 9, and

thence into the chamber 8, whence it is ejected through the orifice 5. By the provision of a plurality of helicall grooves 1'0, as shown in the drawings fourin number, it is obvious that the liquid upon entering the nozzle is broken up, and at the'same time in passing through said grooves is given'a rotary motion, causing the broken up liquid discharged into the chamber 8 to move ina rotary path, and from which chamber the liquid 1s discharged through the orifice 5 into a spherical, mist-like spray, because Vof the knife-edged construction of the same.

While I have shown what I deem to be the preferable form of my device, I do not Wish l to be limited thereto, :le there might be many changes made in the arrangement of parts :ind details of construction without departing from the spirit of my invention.

Having described my 'invention what I claim as new, and desire to secure by Letters Patent, is: i In a device of the class described, n cylindrical member provided with a circular longitudinal bore extending the entire length thereof and threaded at one end, the diameter of said perforation being constant to a point within :i short distance from the -forward extremity of Said member, :1t which point it tapers abruptly to :L minute orifice l
